In the fields of mechanical transmission and conveying, a persistent challenge for engineers has been achieving precise drive within compact spaces while preventing interference between the drive components and the conveyed materials. Addressing this very issue, we proudly present the innovative Ployamide Double-Groove Round Belt Pulley. It is not just a transmission component, it is an efficient solution for optimizing space and enhancing reliability.

Traditional grooved rollers, where grooves are pressed on a steel cylinder body, often risk the O-belt rubbing against or colliding with the conveyed goods. This can lead to product damage, belt slippage, or even drive failure.
Our Polyamide Double-Groove Round Belt Pulley features an innovative end-mount design. It fixes the pulley body with two precision grooves directly onto the end of the roller, thereby physically separating two functional spaces.
1. Drive Space: Located at the roller end, dedicated to installing O-belt, forming an efficient and stable transmission system.
2. Conveyance Space: The main body of the roller remains clean and smooth, dedicated to the smooth conveying of materials. This ingenious structure fundamentally eliminates the possibility of interference between the O-belt and the conveyed goods, ensuring a smooth conveying process and protecting the integrity of product surfaces.
The double grooves pulley can be used in series with O-ring belts, or they can be combined with grooved rollers, making installation and removal straightforward and greatly facilitating equipment assembly and routine maintenance.
Manufactured from high-strength, wear-resistant engineering plastic, it offers characteristics like light weight, low noise operation, corrosion resistance, and self-lubrication. Compared to metal pulleys, it effectively reduces system load, lowers energy consumption, and minimizes belt wear.
Precision injection molding ensures accurate and consistent groove dimensions, providing a perfect fit for O-ring round belts. This not only reduces the risk of belt misalignment and detachment but also enables smoother, more efficient transmission, extending the service life of both belts and the pulley.
